Maintenance & Winterization


The Giant Fountains require no routine maintenance. If the screen becomes clogged, the basket type screen can easily be removed while the fountain is in place and cleaned with a wire brush.


Giant Fountains must be removed in climates that experience cold winters and frozen waters before lakes freeze over. The motor and pump must be stored in a heated area that stays above 32° Fahrenheit or 0° Celsius.
